The horrors of September 11, 2001, unfolded in just under 102 minutes. On that day, 2,996 people died in the worst terrorist attack in modern history.
What followed was 19 years, 10 months, three weeks and two days of war in Afghanistan, with the Department of Defense counting at least 2,325 American military deaths. No one knows exactly how many civilians were killed.
On September 11, 2021, President Joe Biden will try to draw a line under those twin tragedies, paying his respects at the three sites, whose fiery suffering set alight America’s longest war.
